CROSS REFERENCE TO RELATED APPLICATIONS

This application is divisional application of U.S. application Ser. No. 13/519,823, which is a national stage entry under 35 U.S.C. § 371 of International Patent Application No. PCT/US2010/062017, filed 23 Dec. 2010, which claims priority to U.S. Provisional Patent Application No. 61/290,783 filed on 29 Dec. 2009, all of which applications are incorporated herein by reference.

BACKGROUND OF THE INVENTION

Ginger has long been a culinary ingredient, enjoyed particularly for the flavor it provides. Native to southern Asia, ginger is a 2- to 4-foot perennial that produces grass-like leaves up to a foot long and almost an inch wide. Ginger root, as it is called in the grocery store, consists of the underground stem of the plant, with its bark-like outer covering scraped off. Ginger has long been used as a health supplement for humans.

Ginger's modern use dates back to the early 1880s, when it was noticed that ginger-filled capsules reduced nausea during flu. Ginger was then approved as a treatment for indigestion and motion sickness. Ginger has since become widely accepted as a treatment for human nausea. Even some conventional medical texts suggest ginger for the treatment of the nausea and vomiting of pregnancy, although others are more cautious.

Accordingly, the inventors have developed pet food compositions including ginger, which are useful in treating inflammatory conditions, including gastrointestinal disorders and arthritis, and for improvement of the well-being of companion animals, for example, cats and dogs.

SUMMARY OF THE INVENTION

The invention generally encompasses pet food compositions for a companion animal that include an effective amount of ginger to prevent, to ameliorate the symptoms of, or to treat, inflammation or an inflammatory disorders in the companion animal, where the inflammation or inflammatory disorder is an arthritic condition or a gastrointestinal disorder. The arthritic condition may be osteoarthritis, rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis or a local inflammatory joint condition. Gastrointestinal disorders may include irritable bowel disorders and chronic diarrhea.

The pet food compositions of the invention containing ginger may also meet the nutritional requirements for a companion animal (e.g., an amount of protein, an amount of fat, an amount of carbohydrate, and/or an amount of fiber).

The present inventors have examined the effects of ginger in the diet of an animal. The animal may be a companion animal or livestock. The animal may be a dog. The animal may be a cat. Preferred companion animals of the invention are dogs and cats.

DETAILED DESCRIPTION

It is contemplated that the invention described herein is not limited to the particular methodology, protocols, ingredients and reagents described as these may vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present invention in any way.

Unless defined otherwise, all technical and scientific terms used herein have the same meanings as commonly understood by one of ordinary skill in the art to which this invention belongs. Although any methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present invention, the preferred methods, devices and materials are now described. All publications mentioned herein are incorporated by reference for the purpose of describing and disclosing the materials and methodologies that are reported in the publication, which might be used in connection with the invention.

As used herein and in the appended claims, the singular forms “a”, “an”, and “the” include plural reference unless the context clearly dictates otherwise.

As used herein, the term “ginger” refers to the plant Zingiber officinale and derivatives thereof. By way of example, ginger may include products derived from the leaves, stems, seeds, and roots of a ginger plant. Ginger may be in the form of a ground powder, freshly ground, spray dried, freeze dried, wet root, extract, oil, suspension, oil and water, or solution. The ginger may be cooked or raw. An “extract” of ginger herein is any preparation containing substances extracted from ginger, including fluid extracts, tinctures, essential oils, distillates and oleoresins. Extracts of ginger may be prepared by any of the methods described herein or as known in the art by a skilled worker.

The terms “inflammatory bowel disease” or “IBD” refer to an inflammatory condition of the large and sometimes small intestines. The terms also refer to a group of idiopathic gastrointestinal disorders characterized by continuous or recurring abdominal pain or cramping. The pain may range from mild to severe. Pain is frequently associated with altered bowel motility (e.g., diarrhea, constipation or both).

IBD is also characterized by inflammatory infiltrates within the lamina propria of the gastrointestinal tract. IBD encompasses segmental granulomatous enterocolitis, lymphoplasmacytic enteritis, eoisinophilic gastroenterocolitis, lymphocytic gastroenterocolitis, suppurative enterocolitis and histiocytic colitis. These specific types of IBD are characterized based on the type of inflammatory infiltrate found in the lamina propria. The inflammatory infiltrates can be quite variable in terms of severity and cell types, with lymphocytes and plasma cells being the most common cell types. Inflammatory infiltrates may involve the stomach, small bowel and colon. In the cat, for example, the stomach and small bowel are affected most often. In many cases, multiple segments of the bowel are involved and clinical signs may be mixed, reflecting the broad distribution of mucosal lesions. The severity of IBD varies from mild clinical signs to life-threatening protein-losing enteropathies.

IBD may be marked by any of the following symptoms: abdominal pain, vomiting, diarrhea, hematochezia (bright red blood in stools), weight loss, and various associated complaints or diseases like arthritis, pyoderma gangrenosum, and primary sclerosing cholangitis. IBD may also be a result of the following conditions: Crohn's disease, ulcerative colitis, overactive immune system, collagenous colitis, lymphocytic colitis, ischemic colitis, diversion colitis, Behcet's syndrome, infective colitis, and indeterminate colitis.

Mucosal inflammatory infiltrates are responsible for the clinical manifestations of IBD. Mucosal inflammation disrupts normal absorptive processes. Such disruption results in malabsorption and osmotic diarrhea. Altered gut permeability can result in leakage of fluid, protein and blood into the gut lumen. Malabsorbed fats, carbohydrates, and bile acids result in secretory diarrhea. Inflammatory mediators may also directly trigger intestinal secretion and mucus production by goblet cells. Mucosal inflammatory infiltrates may alter intestinal and colonic motility patterns, a mechanism attributed to the influence of prostaglandins and leukotrienes on smooth muscle. Inflammation of the stomach and small bowel stimulates receptors that trigger vomiting. In cats, for example, the most common clinical signs of IBD are chronic vomiting, diarrhea and weight loss.

The term “chronic diarrhea,” or “CD,” refers to a chronic or persistent presence of loose or liquid stool. Diarrhea may be caused by a viral, parasitic, or bacterial infection or it may be a symptom of another condition such as dysentery, cholera, botulism, lactose intolerance, appendicitis, celiac disease, fructose malabsorption, pernicious anemia, loss of pancreatic secretions, ulcerative colitis, ischemic bowel disease, bowel cancer, hormone tumors, or Crohn's disease. Diarrhea may be caused by dysfunction in the digestive system. Secretory diarrhea refers to an increase in the active secretion, or an inhibition of absorption. Osmotic diarrhea refers to too much water drawn into the bowels, often by a shift in the concentration of salt ions such as sodium, potassium, and chloride. Motility-related diarrhea is caused by the rapid movement of food through the intestines (hypermotility). Inflammatory diarrhea occurs when there is damage to the mucosal lining or brush border, which leads to a passive loss of protein-rich fluids, and a decreased ability to absorb these lost fluids.

Inflammation refers to a protective attempt by an organism to remove an injurious stimulus and initiate the healing processes for the tissue affected by the injurious stimulus. Inflammation can be classified as either acute or chronic. Acute inflammation is an initial response to harmful stimuli and is achieved by the increased movement of plasma and leukocytes from the blood into the injured tissues. A cascade of biochemical events propagates and matures the inflammatory response, involving the local vasculature, the immune system, and various cells within the injured tissue. Chronic inflammation, or prolonged inflammation, leads to a progressive shift in the type of cells, which are present at the site of inflammation, and is characterized by simultaneous destruction and healing of the tissue from the inflammatory process.

Apoptosis refers to one of the main types of programmed cell death and involves a series of biochemical events leading to a characteristic cell morphology and death, in more specific terms, a series of biochemical events that lead to a variety of morphological changes, including blebbing, changes to the cell membrane such as loss of membrane asymmetry and attachment, cell shrinkage, nuclear fragmentation, chromatin condensation, and chromosomal DNA fragmentation.

DNA repair refers to a collection of processes by which a cell identifies and corrects damage to the DNA molecules that encode its genome. DNA repair ability of a cell is vital to the integrity of its genome and thus to its normal functioning and that of the organism. Both normal metabolic activities and environmental factors such as UV light and radiation can cause DNA damage, resulting in as many as 1 million individual molecular lesions per cell per day. Many of these lesions cause structural damage to the DNA molecule and can alter or eliminate the cell's ability to transcribe the gene that the affected DNA encodes. Other lesions induce potentially harmful mutations in the cell's genome, which affect the survival of its daughter cells after it undergoes mitosis. Consequently, DNA repair processes are constantly active as it responds to damage in the DNA structure. The rate of DNA repair depends on many factors, such as the particular cell type, age of the cell, and the extracellular environment. A cell that has accumulated a large amount of DNA damage, or one that no longer effectively repairs damage incurred to its DNA, can enter one of three possible states: senescence, apoptosis, or unregulated cell growth.

Oxidative stress refers to an imbalance between the production of reactive oxygen species and a biological system's ability to readily detoxify the reactive intermediates or easily repair the resulting damage. Reactive oxygen species include super oxide, ozone, peroxide and a hydroxyl radical. Oxidative stress causes cellular damage through mechanisms such as damage of DNA, oxidations of polydesaturated fatty acids in lipids, oxidations of amino acids in proteins, and oxidatively inactivate specific enzymes by oxidation of co-factors.

The term “large breed” canine means a canine that generally weighs more than 55 pounds when an adult. The term “regular breed” canine means a canine that weighs less than 55 pounds and more than 20 pounds when an adult. The term “small breed” canine means a canine that weighs less than 20 pounds when an adult. The terms “senior” or “mature adult” refers to the life-stage of an animal. For small or regular breed canines, the “senior” life stage is from about 7 to about 10 years of age. For felines, the “senior” life stage is from about 7 to about 12 years of age. For large breed canines, over 5 years of age represents “senior.”

As used herein the term “compositions of the invention” refers to animal dietary food compositions including ginger. The compositions of the invention include ginger in an amount of about 0.5%, about 1%, about 1.5%, about 2%, about 3%, about 4%, about 5%, about 6%, about 7%, about 8%, about 9%, or about 10% by weight. The compositions of the invention may alleviate inflammatory bowel disorder. The compositions of the invention may alleviate diarrhea. The compositions of the invention may alleviate inflammation. The compositions of the invention may relieve arthritic conditions, for example, osteoarthritis, or less common inflammatory joint diseases in companion animals such as rheumatoid arthritis, psoriatic arthritis or other degenerative joint disorders. The compositions of the invention may alleviate cell apoptosis. The compositions of the invention may improve DNA repair. The compositions of the invention may alleviate protein damage. The compositions of the invention may alleviate oxidative stress.

The composition of the invention can be a liquid or a solid food. Where the composition is a liquid, the ginger can be admixed with other components. Where the composition is a solid, the ginger may be coated on the composition, incorporated into the composition or both.

In various embodiments, the ginger may be added to the animal's food. In certain embodiments, the ginger may be added to the animal's food by a compounder or manufacturer at a site or by an animal's caregiver prior to feeding the animal. In other embodiments, the ginger may be added during the processing of an animal's food, such as during and/or after mixing of other components of the composition that is then packaged and made available to consumers. Such processing may include extrusion, canning, baking and the like or any other method of process of producing pet foods that is known in the art.

As used herein, an “ingredient” refers to any component of a composition.

The term “nutrient” refers to a substance that provides nourishment. In some cases an ingredient may comprise more than one “nutrient,” for example, a composition may comprise fish oil as an ingredient, the oil itself comprising important nutrients such as eicosapentaenoic acid and docosahexaenoic acid. The distinction in these terms is familiar to one of skill in the art.

As contemplated herein, the compositions of the present invention are meant to encompass nutritionally complete and balanced animal feed compositions that additionally comprise ginger. A “nutritionally complete diet” is a diet that includes sufficient nutrients for maintenance of normal health of a healthy animal on the diet.

Nutritionally complete and balanced pet food compositions are familiar to one of skill in the art. For example substances such as nutrients and ingredients suitable for nutritionally complete and balanced animal feed compositions, and recommended amounts thereof, may be found for example, in the Official Publication of The Association of American Feed Control Officials, Inc. (AAFCO), Atlanta, Ga., 2005, or the National Research Council's Nutrient Requirements of Dogs and Cats, The National Academy Press, Washington, D.C., 2006.

For example, a nutritionally complete and balanced dog food composition of the present invention may comprise: about 0 to about 90%, preferably about 5% to 60%, by weight of carbohydrates; about 5% to about 70%, preferably about 10% to about 60%, by weight of protein; about 2% to about 50%, preferably about 5% to about 40%, by weight of fat; about 0.1% to about 20%, preferably about 1% to about 11%, by weight of total dietary fiber; about 0 to about 15%, preferably about 2% to about 8%, by weight of vitamins and minerals, antioxidants, and other nutrients which support the nutritional needs of the animal; and about 0.5% to about 1.5%, preferably 2%, more preferably 1%, by weight of ginger.

For example, a nutritionally complete and balanced cat food composition of the present invention may comprise: about 0 to about 90%, preferably about 5% to 50%, by weight of carbohydrates; about 5% to about 70%, preferably about 20% to about 60%, by weight of protein; about 2% to about 50%, preferably about 5% to about 40%, by weight of fat; about 0.1% to about 20%, preferably about 1% to about 11%, by weight of total dietary fiber; about 0 to about 15%, preferably about 2% to about 8%, by weight of vitamins and minerals, antioxidants, and other nutrients which support the nutritional needs of the animal; and about 0.5% to about 1.5%, preferably 2%, more preferably 1%, by weight of ginger.

As used herein, the term “supplement(s)” include, but are not limited to, a feed used with another feed to improve nutritive balance or performance of the total. Supplements include, but are not limited to, compositions that are fed undiluted as a supplement to other feeds, offered free choice with other parts of an animal's ration that are separately available, or diluted and mixed with an animal's regular feed to produce a complete feed. The Official Publication of The Association of American Feed Control Officials, Inc., for example, contains a discussion relating to supplements. Supplements may be in various forms including, for example, powders, liquids, syrups, pills, encapsulated compositions, and the like.

The term “carbohydrate” as used herein includes polysaccharides (e.g., starches and dextrins) and sugars (e.g., sucrose, lactose, maltose, glucose, and fructose) that are metabolized for energy when hydrolyzed. Examples of carbohydrates suitable for inclusion in the compositions disclosed herein include, but are not limited to, corn, grain sorghum, wheat, barley, and rice.

As used herein, “soluble fiber” refers to dietary fiber that attracts water during digestion and slows the rate of nutrient absorption and is typically found in, e.g., oat bran, seeds, beans, and certain fruits and vegetables such as beet pulp, guar gum, chicory root, psyllium, pectin, blueberry, cranberry, squash, apples, oats, beans, citrus, barley and peas. As used herein, the term encompasses any source of soluble fiber suitable for the compositions disclosed herein as would be evident to one of skill in the art.

The term “antioxidant” means a substance that is capable of reacting with free radicals and neutralizing them. Illustrative examples of such substances include beta-carotene, selenium, coenzyme Q10 (ubiquinone), luetin, tocotrienols, soy isoflavones, S-adenosylmethionine, glutathione, taurine, N-acetylcysteine, vitamin E, vitamin C, lipoic acid and L-carnitine. Examples of foods containing useful levels of one or more antioxidants include but are not limited to, ginkgo bilboa, green tea, broccoli, citrus pulp, grape pomace, tomato pomace, carrot spinach, and a wide variety of fruit meals and vegetable meals. It will be understood by one of skill in the art that while units of antioxidants may be provided herein as “ppm”, appropriate amounts of antioxidants may also be provided as “IU/kg” where appropriate and customary for a given antioxidant such as, e.g., Vitamin E.

As used herein, “improving” or “enhancing” the quality of life of an animal refers to an improvement or enhancement in one or more characteristics selected from a group consisting of alertness, vitality, protection of cartilage, maintenance of muscle mass, digestibility, and skin and pelage quality. Additionally, improvement/enhancement in blood clotting and platelet activation and aggregation, bone and muscle integrity, inflammatory responses, cartilage degradation and pain response, DNA damage and repair pathways, neural function, glycogen synthesis and degradation, glycolysis, gluconeogenesis, the pentose phosphate pathway and electron transport are also contemplated.

An “improvement” or an “enhancement” in a characteristic or biological pathway refers to a modification in said characteristic or biological pathway such that there is a tendency for the characteristic or pathway to appear and/or function normally and with less tendency to reflect pathological changes in the characteristic or pathway that, e.g., may be typical of a senior animal.

As used herein, methods to “treat” an animal suffering from a disease or disorder is also meant to encompass methods to prevent and/or to ameliorate the disease or disorder as well.

The invention generally encompasses pet food compositions for a companion animal comprising an effective amount of ginger to prevent inflammation or an inflammatory disorder in a companion animal.

In certain embodiments, the effective amount of ginger is at least 0.5% by weight ginger. In other embodiments of the invention ginger is present in a range of about 0.5% to about 2% by weight on a dry matter basis.

In certain embodiments, the fiber food ingredient is obtained from a variety of sources such as vegetable fiber sources, for example, cellulose, beet pulp, peanut hulls, and soy fiber.

In certain embodiments, the nutritional balancing agents are obtained from a variety of sources known to skilled artisans, for example, vitamin and mineral supplements and food ingredients. Vitamins and minerals can be included in amounts required to avoid deficiency and maintain health. These amounts are readily available in the art. The National Research Council (NRC) provides recommended amounts of such nutrients for farm animals. See, e.g., Nutrient Requirements of Swine (10th Rev. Ed., Nat'l Academy Press, Wash. D.C., 1998), Nutrient Requirements of Poultry (9th Rev. Ed., Nat'l Academy Press, Wash. D.C., 1994), Nutrient Requirements of Horses (5th Rev. Ed., Nat'l Academy Press, Wash. D.C., 1989). The Association of American Feed Control Officials Inc. (AAFCO) provides recommended amounts of such nutrients for dogs and cats. See, e.g., the Official Publication of The Association of American Feed Control Officials Inc. Vitamins generally useful as food additives include vitamin A, vitamin B1, vitamin B2, vitamin B6, vitamin B12, vitamin D, biotin, vitamin K, folic acid, inositol, niacin, and pantothenic acid. Minerals and trace elements useful as food additives include calcium, phosphorus, sodium, potassium, magnesium, copper, zinc, chloride, iron, selenium, iodine, and iron.

The compositions can contain additional ingredients intended to maintain or improve the health of the animal, for example, supplements, medications, herbs, holistic drugs and compositions, and the like.

The composition of the invention may include one or more additional ingredients to prevent or treat one or more diseases or conditions. The component in the diet which accomplishes this may be an antioxidant or mixture thereof. An antioxidant is a material that quenches a free radical. Examples of such materials include foods such as Ginkgo Biloba, citrus pulp, grape pomace, tomato pomace, carrot and spinach, all preferably dried, as well as various other materials such as beta-carotene, selenium, coenzyme Q10 (ubiquinone), lutein, tocotrienols, soy isoflavones, S-adenosylmethionine, glutathione, taurine, N-acetylcysteine, Vitamin E, Vitamin C, alpha-lipoic acid, 1-carnitine and the like. Vitamin E can be administered as a tocopherol or a mixture of tocopherols and various derivatives thereof such as esters like vitamin E acetate, succinate, palmitate, and the like. The alpha form is preferable but beta, gamma and delta forms can be included. The d form is preferable but racemic mixtures are acceptable. The forms and derivatives will function in a Vitamin E like activity after ingestion by the pet. Vitamin C can be administered in this diet as ascorbic acid and its various derivatives thereof such as calcium phosphate salts, cholesteryl salt, 2-monophosphate, and the like which will function in a vitamin C like activity after ingesting by the pet. They can be in any form such as liquid, semisolid, solid and heat stable form. L-carnitine can be administered in the diet and various derivatives of carnitine such as the salts such as the hydrochloride, fumarate and succinates, as well as acetylated carnitine, and the like can be used.

The quantities administered in the diet, all as wt % (dry matter basis) of the diet, are calculated as the active material, per se, that is measured as free material. The maximum amounts employed should not bring about toxicity. At least about 100 ppm or at least about 150 ppm of Vitamin E can be used. A preferred range of 500 to 1,000 ppm can be employed. Although not necessary, a maximum of about 2000 ppm or about 1500 ppm is generally not exceeded. With respect to Vitamin C, at least about 50 ppm is used, desirably at least about 75 ppm and more desirably at least about 100 ppm. A non-toxic maximum can be employed. The quantity of lipoic acid can vary from at least about 25, desirably at least about 50 ppm, more desirably about 100 ppm. Maximum quantities can vary from 100 ppm to 600 ppm or to an amount which remains non-toxic to the pet. A preferred range is from 100 ppm to 200 ppm. For 1-carnitine about 50 ppm, desirably about 200 ppm, more desirably about 300 ppm for canines are a useful minimum. For felines, slightly higher minimums of 1-carnitine can be employed such as about 100 ppm, 200 ppm, and 500 ppm. A non-toxic maximum quantity can be employed, for example, less than about 5,000 ppm. For canines, lower quantities can be employed, for example, less than about 5,000 ppm. For canines, a preferred range is 200 ppm to 400 ppm. For felines, a preferred range is 400 ppm to 600 ppm. Beta-carotene at 1-15 ppm can be employed. Selenium at 0.1 up to 5 ppm can be employed. Lutein at least about 5 ppm can be employed. Tocotrienols at least about 25 ppm can be employed. Coenzyme Q10 at least about 25 ppm can be employed. S-adenosylmethionine at least about 50 ppm can be employed. Taurine at least about 1000 ppm can be employed. Soy isoflavones at least about 25 ppm can be used. N-acetylcysteine at least about 50 ppm can be used. Glutathione at least about 50 ppm can be used. Gingko Biloba at least 50 ppm of extract can be used.

In certain embodiments, the compositions further include an effective amount of at least one substance selected from the group consisting of glucosamine, chondroitin, chondroitin sulfate, methylsulfonylmethane (“MSM”), creatine, antioxidants, Perna canaliculata, omega-3 fatty acids, omega-6 fatty acids and mixtures thereof.

In certain embodiments, the composition can be a treat. Treats include compositions that are given to an animal to entice the animal to eat during a non-meal time, for example, dog bones for canines. Treats may be nutritional wherein the composition includes one or more nutrients and/or may have a food-like composition. Non-nutritional treats encompass any other treats that are non-toxic. The composition or components are coated onto the treat, incorporated into the treat, or both. Treats of the invention can be prepared by an extrusion or baking process similar to those used for dry food. Other processes also may be used to either coat the composition on the exterior of existing treat forms or inject the composition into an existing treat form.

In certain embodiments, the composition can be a toy. Toys include chewable toys such as artificial bones. The ginger can form a coating on the surface of the toy or on the surface of a component of the toy, be incorporated partially or fully throughout the toy, or both. There are a wide range of suitable toys currently marketed, for example, U.S. Pat. Nos. 5,339,771, 5,419,283, and references disclosed therein. This invention provides both partially consumable toys, for example, toys including plastic components, and fully consumable toys, for example, rawhides and various artificial bones. The invention preferably provides toys for use by a dog or a cat.

In certain embodiments, the companion animal is a senior animal.

The present inventors have identified the effects of ginger to reduce inflammatory markers and improve markers of cartilage synthesis in cats and dogs with arthritis. Feeding a food containing 0.5% ginger reduced IL-1 beta and IL-6, and tended to lower IFN-gamma markers associated with inflammation/arthritis. In addition, ginger stimulated cartilage synthesis as indicated by a marker (CPII) of collagen synthesis and improved the ratio of collagen synthesis to degradation (CPII:CTXII) with a greater percent increase observed in arthritic cats (57%) compared to non-arthritic (8%). In dogs, feeding a control food+1% ginger resulted in improvements in markers of bone formation, bone turnover, and BAP:NTX ratio. This suggests that dogs fed ginger had improved balance between synthesis and turnover of bone that is normally upset in arthritic animals.

Ginger may be in the form of the ground powder, freshly ground, spray dried or freeze-dried, wet root, extract, or oils, can be incorporated in foods or drinks.

Ginger may be incorporated into a food or used as a nutritional supplement in many different forms including ginger extracts such as ginger powder extracts, ginger fluid extracts, ginger powder, and one or more active compounds of ginger; parts of or whole ginger plants; tinctures thereof and mixtures thereof. In addition, for any specific active compound of ginger for which suitable synthesis routes are known, the active compound can be prepared synthetically. Preferably, the second ingredient of the nutritional supplement of the present invention is selected from ginger extract, and ginger root powder.

Extracts of ginger can be prepared from fresh or dried ginger root which is prepared by extraction with methanol, ethanol, isopropanol, acetone, ethyl acetate, carbon dioxide, hexane, methylene chloride, chloroform or other solvents or solvent mixtures of comparable polarity.

Ginger contains 1-4% essential oil (oleoresin). Many chemical investigations have been carried out on the constituents of the essential oil of ginger.

Without being bound by theory, the benefits of the invention may be the result of physiological effects from the addition of ginger or derivatives thereof to an animal's diet. Similarly, the antioxidants, choline, and other nutrients may play a role in enhancing a senior animal's quality of life.

The invention encompasses food compositions or supplements wherein ginger is present in an effective amount to treat, manage, or ameliorate a condition in an animal. The effective amount of ginger may vary depending on such factors as the patient being treated, the particular mode of administration, the activity of the particular active ingredients employed, the age, bodyweight, general health, sex and diet of the patient, time of administration, rate of excretion, the particular combination of ingredients employed, the total content of the main ingredient of the nutritional supplement or nutritionally complete diet, and the severity of the illness or symptom. It is within the skill of the person of ordinary skill in the art to account for these factors.

A “food” is a nutritionally complete diet for the intended recipient animal (e.g., domestic cat or domestic dog). A “nutritionally complete diet” is a diet that includes sufficient nutrients for maintenance of normal health of a healthy animal on the diet. The methods of this invention utilize compositions that are not intended to be restricted by any specific listing of proteinaceous or fat ingredients or product form. The compositions can be prepared in, for example, a dry, canned, wet, or intermediate moisture form using conventional pet food processes. In some embodiments, the moisture content is from about 5% to about 90% of the total weight of the composition. In other embodiments, the moisture content is from about 65% to about 75% of the total weight of the composition.

The food composition may further contain other ingredients such as corn, poultry meal, grease, palatability enhancers, potassium chloride, iodized salt, calcium carbonate, choline chloride, mineral premix, preservative, vitamin premix. The food may contain protein. The protein may be present in about 5 to 50% by weight. The protein may be animal protein. Animal protein may be part of the total protein. Animal protein may be 50%, 70%, 80%, 90%, 95%, 99% or 100% of the total protein. The food may contain antioxidants, such as vitamin E. Antioxidant may be present in between about 0.0001 U/g and 3.0 U/g food, such as, e.g., 0.18 U/g. The food may contain eicosapentaenoic acid (EPA) at between 1% and 5% by weight. Fatty acids may also be included such as n-3 and n-6 fatty acids. Fatty acids may be present in about 0.05% to 5% by weight. n-3 fatty acids may be present in about 0.0001% to 2%. n-6 fatty acids may be present in about 0.5% to 5% by weight. The food may contain fiber, such as crude fiber. Fiber may be present in between 0.1% and 20% by weight.

The effective amount of the nutritional supplement will vary depending on such factors as the patient being treated, the particular mode of administration, the activity of the particular active ingredients employed, the age, bodyweight, general health, sex and diet of the patient, time of administration, rate of excretion, the particular combination of ingredients employed, the total content of the main ingredient of the nutritional supplement, and the severity of the illness or symptom. It is within the skill of the person of ordinary skill in the art to account for these factors.

The ginger dietary foods or supplements of the present invention may be formulated using a safe and effective amount of ginger as discussed herein to provide one or more of the beneficial effects of the invention described herein, and one or more of the optional ingredients which may be obtained from slippery elm or green tea, as well as one or more of the additional optional ingredients described below.

Although the methods of the invention may improve an animal's quality of life by enhancing all of the above described characteristics or improving all of the described biological pathways, it is not necessary to demonstrate substantial improvements in each of the characteristics or pathways to achieve the “enhanced quality of life” as defined herein.

When the compositions are administered to an animal, the animal experiences an enhanced quality of life, e.g., decreased inflammatory responses, increased collagen synthesis, increased cartilage synthesis, reduced diarrhea, reduced arthritis, decreased cartilage degradation, DNA damage and repair pathways, glycogen synthesis and degradation, glycolysis, gluconeogenesis, the pentose phosphate pathway and the electron transport pathway as indicated by overall beneficial changes at the cellular level. Methods for determining these measurements of quality of life are known to skilled artisans. Potential markers of antioxidant status may include serum vitamin E, ORAC, glutathione peroxidase, alkanels, and/or cell damage indicators. Further, vitality can be measured by various means, including an analysis of metabolism and antioxidant markers, as well as through clinical studies with follow-up questions to participating pet owners. Similarly, cartilage protection can be measured by various means, including an analysis of arthritis biomarkers. Potential arthritis biomarkers may include type II collagen synthesis, matrix metalloproteinase, osteocalcin, alkaline phosphatase activity, COMP, and fragments of cartilage damage. Muscle mass maintenance can be measured by various means, including an analysis of body composition, and digestibility can be measured by various means, including clinical studies with follow-up questions to participating pet owners and animal feeding to determine the percentage of nutrients digested. Skin and pelage quality can be measured by various means, including clinical studies with follow-up questions to participating pet owners.

The methods of the invention are useful for enhancing the quality of life of animals, including primates (e.g., monkeys, chimpanzees, etc.), companion animals (e.g., dogs, cats, horses, etc.), farm animals (e.g., goats, sheep, swine, cattle, etc.), laboratory animals (e.g., mice, rats, etc.), birds (e.g., domestic birds such as canaries, parrots, etc. and commercial birds such as chickens, ducks, turkeys, etc.), rodents (e.g., hamsters, guinea pigs, gerbils, rabbits, hedgehogs, ferrets, chinchillas, etc.), and wild, exotic, and zoo animals (e.g., wolves, bears, deer, etc.). In various embodiments, the animal is a cat, a dog, or a horse.

The food compositions comprise ginger. Ginger may be present at about 0.5%, about 1%, about 1.5%, about 2%, about 3%, about 4%, about 5%, about 6%, about 7%, about 8%, about 9%, or about 10% by weight. The food composition may comprise other ingredients. The other ingredients may be selected from water, protein, fiber, carbohydrate, fat, soluble fiber, insoluble fiber, docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), omega-3 fatty acids, omega-6 fatty acids, tocopherols, ascorbate, calcium, chloride, cysteine, magnesium, manganese, methionine, phosphorous, potassium, iron, and essential amino acids.

When the composition is an animal food, vitamins and minerals preferably are included in amounts required to avoid deficiency and maintain health. These amounts are readily available in the art. The National Research Council (NRC), for example, provides recommended amounts of such ingredients for farm animals. See, e.g., Nutrient Requirements of Swine (10th Rev. Ed., Nat'l Academy Press, Wash. D.C., 197298), Nutrient Requirements of Poultry (9th Rev. Ed., Nat'l Academy Press, Wash. D.C., 1994), Nutrient Requirements of Horses (Fifth Rev. Ed., Nat'l Academy Press, Wash. D.C., 1989), Nutrient Requirements of Dogs and Cats (Nat'l Academy Press, Wash. D.C., 2006). The Association of American Feed Control Officials Inc. (AAFCO), for example, provides recommended amounts of such ingredients for dogs and cats. See, e.g., the Official Publication of The Association of American Feed Control Officials Inc. Examples of vitamins useful as food additives include vitamin A, B1, B2, B6, B12, C, D, E, K, H (biotin), K, folic acid, inositol, niacin, and pantothenic acid. Examples of minerals and trace elements useful as food additives include calcium, phosphorus, sodium, potassium, magnesium, copper, zinc, chloride, and iron salts.

The methods of the present invention include compositions that may further contain other additives known in the art. Such additives are present in amounts that do not impair the purpose and effect provided by the invention. Examples of additives include, for example, substances with a stabilizing effect, processing aids, substances that enhance palatability, coloring substances, and substances that provide nutritional benefits.

Stabilizing substances include, for example, substances that tend to increase the shelf life of the composition. Potentially suitable examples of such substances include, for example, preservatives, antioxidants, synergists and sequesterants, packaging gases, stabilizers, emulsifiers, thickeners, gelling agents, and humectants. Examples of emulsifiers and/or thickening agents include, for example, gelatin, cellulose ethers, starch, starch esters, starch ethers, and modified starches.

Additives for coloring, palatability, and nutritional purposes include, for example, colorants (e.g., iron oxide, such as the red, yellow, or brown forms); sodium chloride, potassium citrate, potassium chloride, and other edible salts; vitamins; minerals; and flavoring. Such additives are known in the art. See, e.g., U.S. Pat. No. 3,202,514. See also, U.S. Pat. No. 4,997,671. Flavorants include, for example, dairy product flavorants (e.g., milk or cheese), meat flavorants (e.g., bacon, liver, beef, poultry, or fish), oleoresin, pinacol, and the various flavorants identified in the trade by a FEMA (Flavor Extract Manufacturers Association) number. Flavorants help provide additional palatability, and are known in the art. See, e.g., U.S. Pat. No. 4,997,672. See also, U.S. Pat. Nos. 5,004,624, 5,114,704, 5,532,010, and 6,379,727. The concentration of such additives in the composition typically may be up to about 5% by weight. In some embodiments, the concentration of such additives (particularly where such additives are primarily nutritional balancing agents, such as vitamins and minerals) is from about 0% to about 2.0% by weight. In some embodiments, the concentration of such additives (again, particularly where such additives are primarily nutritional balancing agents) is from about 0% to about 1.0% by weight.

Supplements include, for example, a feed used with another feed to improve the nutritive balance or performance of the total. Supplements include compositions that are fed undiluted as a supplement to other feeds, offered free choice with other parts of an animal's ration that are separately available, or diluted and mixed with an animal's regular feed to produce a complete feed. The AAFCO, for example, provides a discussion relating to supplements in the Official Publication of The Association of American Feed Control Officials Inc. Supplements may be in various forms including, for example, powders, liquids, syrups, pills, encapsulated compositions, and the like.

Treats include, for example, compositions that are given to an animal to entice the animal to eat during a non-meal time. Treats for canines include, for example, dog bones. Treats may be nutritional, wherein the composition comprises one or more nutrients, and may, for example, have a composition as described above for food. Non-nutritional treats encompass any other treats that are non-toxic.

The invention may further provide ginger in a pet toy, wherein the toy is likely to enter the pet's oral cavity. Toys include, for example, chewable toys. Toys for dogs include, for example, artificial bones. There is a wide range of suitable toys currently marketed. See, e.g., U.S. Pat. No. 5,339,771 (and references disclosed in U.S. Pat. No. 5,339,771). See also, e.g., U.S. Pat. No. 5,419,283 (and references disclosed in U.S. Pat. No. 5,419,283). The invention provides both partially consumable toys (e.g., toys comprising plastic components) and fully consumable toys (e.g., rawhides and various artificial bones). It should be further recognized that this invention provides toys for both human and non-human use, particularly for companion, farm, and zoo animal use, and particularly for dog, cat, or bird use.

In preparing a composition for use with the methods of the present invention, any ingredient (e.g., fish oil) generally may, for example, be incorporated into the composition during the processing of the formulation, such as during and/or after mixing of other components of the composition. Distribution of these components into the composition can be accomplished by conventional means. In one embodiment, ground animal and poultry proteinaceous tissues are mixed with the other ingredients, including fish oils, cereal grains, other nutritionally balancing ingredients, special-purpose additives (e.g., vitamin and mineral mixtures, inorganic salts, cellulose and beet pulp, bulking agents, and the like); and water that is sufficient for processing is also added.

Methods of the present invention include utilizing compositions that can be prepared in a dry form using conventional processes. In one embodiment, dry ingredients, including, for example, animal protein sources, plant protein sources, grains, etc., are ground and mixed together. Moist or liquid ingredients, including fats, oils, animal protein sources, water, etc., are then added to and mixed with the dry mix. The mixture is then processed into kibbles or similar dry pieces. Kibble is often formed using an extrusion process in which the mixture of dry and wet ingredients is subjected to mechanical work at a high pressure and temperature, and forced through small openings and cut off into kibble by a rotating knife. The wet kibble is then dried and optionally coated with one or more topical coatings which may include, for example, flavors, fats, oils, powders, and the like. Kibble also can be made from the dough using a baking process, rather than extrusion, wherein the dough is placed into a mold before dry-heat processing.

The compositions may also be designed to be easier to chew. Canine and feline foods are typically formulated based on life stage (age), size, body composition, and breed. In the methods of this invention, some embodiments address specific nutritional differences between senior regular or small breed dogs, large breed dogs, and cats.

All percentages expressed herein are on a weight by dry matter basis unless specifically stated otherwise.

SPECIFIC EMBODIMENTS OF THE INVENTION

The invention is further described in the following examples. The examples are merely illustrative and do not in any way limit the scope of the invention as described and claimed.

Example 1 Effect of Ginger in Cats with Chronic Diarrhea and Inflammatory Bowel Disease

The objective of this study was to determine the effect of ginger on the clinical symptoms in cats with chronic diarrhea or inflammatory bowel disease. Two groups of cats, a healthy control group and a test group of cats with chronic diarrhea or inflammatory bowel disease, were fed a baseline food for 2 weeks followed by the same baseline food containing 1% ginger root powder. Stool quality was measured daily.

Table 1 shows the nutrient content of the food. It was found that the food was very similar except for the incorporation of ginger in the food. There were no added fish oil or other antioxidants at levels that may be confounding in the results. Table 2 shows the frequency of stool quality of stools collected daily from the cats during the control food phase and the test food phase.

The results showed that consumption of ginger as incorporated in the kibble significantly improved stool quality in cats with inflammatory bowel disease. It was found that by consuming the kibbles with added ginger cats with inflammatory bowel disease had significantly lower poor stools (9.8 vs. 26.2%) and higher good stools (42.7 vs. 32.1%). The food even slightly improved stool quality in normal cats although the stool quality was already very good. The healthy cats did not have any diarrhea episodes in the 3 week test period and had higher percentage of good stools (91% compared to 88%).

Example 2 Effect of Ginger on Stool Quality in Dogs with Chronic Diarrhea

The objective of this study is to determine the effect of ginger on the clinical symptoms in dogs with chronic diarrhea. Two groups of dogs, a healthy control group and a test group of dogs with chronic diarrhea were fed a baseline food for 2 weeks followed by the same baseline food containing 1% ginger root powder. Stool quality was measured daily.

The dietary intervention with 1% ginger resulted in an improvement in clinical symptoms in animals with chronic diarrhea or inflammatory bowel disease.

Example 3 Ginger in Canine and Feline Senior Diet

Methods

Twenty senior cats and twenty senior dogs were utilized to determine the effects of ginger to improve markers of arthritis. In both cats and dogs, 10 had radiographic evidence of arthritis. A control food was fed for 14 days prior to feeding the control food+the test ingredient (Ginger). Ginger was fed for 28 days with samples taken at baseline (day 0) and then at study completion (day 28). Cartilage markers were measured in serum using ELISA kits and procedures to determine biomarker concentrations.

Data were analyzed using a two-way paired t-test to determine the change in marker levels with the hypothesis that the change is different from zero.

Results

Table 5 shows arthritis biomarker values for ten normal and ten arthritic cats fed a control formula enhanced with 1% ginger for 28 days. With the exception of ratios, analysis was performed on natural log transformed values. Means and SED are antilog values of log transformed data. Ratios were calculated and analyzed using untransformed data.

What is claimed is:
 1. A method for treating inflammation or an inflammatory condition in a companion animal in need thereof, comprising: measuring a baseline level of expression of one or more inflammatory biomarkers in the companion animal in need thereof; treating the companion animal in need thereof by administering to the companion animal a pet food composition comprising an effective amount of ginger to treat the inflammation or inflammatory condition in the companion animal, wherein the inflammatory condition is inflammatory bowel disease; measuring a change in the level of expression of the one or more inflammatory biomarkers relative to the baseline level of expression in the companion animal in need thereof, thereby indicating treatment of the inflammation or inflammatory condition, wherein measuring the change in the level of expression of the one or more biomarkers relative to the baseline level of expression comprises measuring an increase in biomarker C-propeptide of type II collagen (CPII).
 2. The method of claim 1, wherein the companion animal is a dog or a cat.
 3. The method of claim 1, wherein the effective amount of ginger is at least 0.05% by weight of the pet food composition.
 4. The method of claim 1, wherein the composition further comprises at least one of an amount of protein, an amount of fat, an amount of carbohydrate, and an amount of fiber.
 5. The method of claim 4, wherein the amount of protein is about 5 wt. % to about 70 wt. % based on the total weight of the composition.
 6. The method of claim 4, wherein the amount of fat is about 2 wt. % to about 50 wt. % based on the total weight of the composition.
 7. The method of claim 1, wherein the pet food composition further comprises L-tryptophan.
 8. The method of claim 1, wherein the pet food composition further comprises one or more of vitamin E, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), other n-3 fatty acids, n-6 fatty acids, crude fiber, or combinations thereof.
 9. The method of claim 1, wherein the ginger is present in an amount of from about 1% to about 10% by weight of the pet food composition.
 10. The method of claim 1, wherein the ginger is present in an amount of from about 1% to about 5% by weight of the pet food composition.
 11. The method of claim 1, wherein measuring the change in the level of expression of the one or more biomarkers relative to the baseline level of the expression further comprises measuring a decrease in IL-1 beta.
 12. The method of claim 1, wherein measuring the change in the level of expression of the one or more biomarkers relative to the baseline level of the expression further comprises measuring a decrease in IL-6.
 13. The method of claim 1, wherein measuring the change in the level of expression of the one or more biomarkers relative to the baseline level of the expression further comprises measuring a decrease in IL-1 beta and IL-6.
